Pierre Berthier was born in Nemours. After studying at the École Polytechnique, he went to the École des Mines, where he became chief of the laboratory in 1816. In 1821, while working in the village of Les Baux-de-Provence, in southern France, he discovered the rock bauxite, named for the place of its discovery. He also discovered the mineral Berthierite, which was named after him. In addition to numerous contributions in mineralogy and mining, Berthier is also noted for his research into blast furnaces and for the utilization of phosphates by plants.
